How do I add a MiniBoost to my system?

Should you find the need to add DC-DC charging, your best option in most cases is to you use the Miniboost.

Installing a MiniBoost is incredibly easy and can be performed in only a few minutes. 

Check the Aux line in from the tow vehicle:

Ensure that the grey Anderson line is ignition switched. You can use an ignition switched relay in the car to do this. Note that if you choose a Voltage Sensitive Relay (VSR) without an ignition override, your car may turn this line off while driving, preventing any charge going through. If you don't have this, you will need to remember to disconnect your grey Anderson plug every time you stop the car. failure to do so will flatten your starter battery. 

BP35-II Systems

1. Remove the Auxiliary line in from the "Aux+" on the bottom right of the BP35-II
2. Connect the MiniBoost's Orange wire to your AX cable. This will power the unit from your grey Anderson plug on the tow vehicle.
3. Connect the MiniBoost's Red wire to the "Aux+" terminal on the BP35-II, preferably with a suitably rated terminal connection such as the ring terminal that is currently there. 
4. Connect both black and white cables together to the "Batt-" connection, preferably using a suitable connecter. if you cannot find a connector that fits both cables, you can use separate connectors, though it will be slightly more difficult to fit the additional connecter onto the "Batt-" terminal
5. Mount the MiniBoost nearby. Try to mount it in a way that will allow easy access to the fuse on the rear.

BP35 mk1 Systems:

The easiest connection method is to use male spade connectors for the input side of the MiniBoost and Female one for its output.

1. Remove the Positive Auxiliary line in (normally Red)  from the "Ax +" on the bottom right of the BP35
2. Connect the MiniBoost's Orange wire to your Positive Auxiliary line cable. If you use a male spade connector, it will make it far easier and you can plug it straight in.
3. Remove the Negative Auxiliary line in (normally Black)  from the "Ax -" on the bottom right of the BP35
4. Connect the Miniboost's White wire to your Negative Auxiliary cable. Once again, it's best to use a male spade connector to allow you to plug straight in.
5. Connect the MiniBoost's Red output cable to the BP35's AX+ terminal using a female spade connector.
6. Connect the MiniBoost's Black output cable to the BP35's AX- terminal using another female spade connector. 
7. Mount the MiniBoost nearby. Try to mount it in a way that will allow easy access to the fuse on the rear.

Genius-II

1. Remove the Red wire from the "DC in" on the bottom right of the Genius-II
2. Connect the MiniBoost's Orange wire to your AX cable. This will power the unit from your grey Anderson plug on the tow vehicle.
3. Connect the MiniBoost's Red wire to the "DC in" terminal on the Genius-II, preferably with fork terminal connector.
4. Connect both black and white cables together to the "Bat -" connection, again using a fork connector. If you cannot find a connector that fits both cables, you can use separate connectors, though it will be slightly more difficult to fit the additional connecter onto the "Bat -" terminal
5. Mount the MiniBoost nearby. Try to mount it in a way that will allow easy access to the fuse on the rear.

The Miniboost is fine for use with lithium batteries when used in conjunction with a battery management system such as the BatteryPlus35-II-HA. The difference in voltage is negligible between it and the MiniBoost Pro at 14·4 volts vs 14·6 volts. This difference is reduced further when the blocking diode on the Auxiliary input lines drops around half a volt off the incoming voltage. The reason this doesn't affect the charge is that the Battery Management Systems are only using this auxiliary input to augment the power being supplied from the solar system. The incoming power from the solar line is what takes the battery from the 13·9-14·1 volts up to the full charge of 14·4 volts for lead-acid and 14·6 volts for lithium. 

The MiniBoost Pro is designed as s standalone system for use in utes and 4wds. Due to the protection systems built into the BP35, it won't switch on immediately and will remain off for the first fifteen minutes that the car is running, diminishing its 2 amp increased current throughput.
